WIND-ENGINE.

SPECEFICATION forming part of Letters Patent No. 305,114, datedSeptember 16, 1884.

Application filed March 1, 1884. (No model.)

To all whom, it may concern.-

Be it known that I, HARRY It. STEVENS, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful VVind-Engine, of which thefollowing is a specification, reference being had to the accompanyingdrawing.

This invention has relation to wind-engines, and is designed to providemeans for automatically regulating the length of the stroke of thepump-rod by the force of the wind; and it consists in the constructionand novel arrangement of parts, as will be hereinafter fully described,and particularly pointed out in the claims.

The figure of the drawing is a perspective View of a wind-engine towhich my improved stroke-regulatin g mechanism is shown applied.

Referring by letter to the accompanying drawing, a designates thederrick, which supports the operative mechanism of the windengine. I)designates the wheel-shaft, and e the wind-wheel. The wheel-shaft b ismounted in suitable bearin gs in the uprights rising from thederrick-platform, and is provided on the wrist-pin or crank-pin d with afriction-roller, d, as shown.

Pivoted at one end in an upright or extension, e, is a lever, f, towhich the upper end of the pump-rod g is pivoted, the forward or freeend of said lever f working vertically between two vertical guides, h h,which prevent lateral movement of said lever f. The lever f is pivotedabove the friction-roller d, and

operates in the same vertical plane therewith. A bed-piece, i, isarranged below the lever f, and on this bed-piece i the horizontal faceof a block or wedge, 73, having its upper face inclined, as shown,rests, and is connected with mechanism by which it is automaticallymoved 7 back and forward under the lever f, as will be tain conditionsof the wind after it has been moved from said normal position undercertain other conditions of the wind. The lever is is connected at aproper distance above its hinged lower end by a short hinged rod, 01.,to the head of the block or wedge i, and when the lever is is in itsnormal position the thickest portion of the wedge t" is directly underthe lever f.

The pump -.rod, when constructed of iron tubing, is sufficiently heavyto fall of its own weight after the lever f has been raised by thefrictionroller on the crank-pin; but where the pump-rod is too light tofall of its own weight after having been raised,a weight, 0, is attachedto the lever f, to insure the downward stroke of the pump-rod.

It will be seen from the foregoing description that the crank providedwith the frictionroller on the wheel-shaft operates the lever f in anupward direction only to its fullest height and then leaves it to fallby the weight of the rod to make the downward stroke, or the weight onthe lever f, in case one is used on said lever. It will be furthernoticed that the length of the downward stroke is regulated by theposition of the wedge 77 under the lever f, as the lever will fall onlyas far as the wedge, which will stop its descent, and consequently thedescent of the pump-rod which is pivoted to it. The position of thewedge is controlled by the strength or force of the wind exerted 011 thevane Z at the upper end of the lever k. \Vhen the wind is light, and butlittle power can be exerted by the wind-wheel, the lever is and vane lare held by the spring in their normal vertical position, the springhaving its full force on the wedge to move it in when thefriction-roller raises the lever f up from the wedge in making theupstroke. As the lever f falls, it will fall upon the highest part ofthe wedge, thereby making the shortest possible stroke, and pumping theminimum quantity of water at the shortest stroke, which requires theleast power. As the wind increases, so as to overcome the force of thespring, the wedge will be drawn outward below the lever f as the vane Zcarries the lever 76 down toward the wheel. The farther the vaneZ iscarried down by the wind the farther the wedge will be drawn out, andthe more the length of the downward stroke is increased. The lever f israised from the wedge at each upward stroke of the pump-rod, so that asthe wind lightens the spring is perfectly free to move the wedge in asfar as the wind will permit it, so that the length of the stroke isvaried as the force of the wind varies, and the automatic adjustment isadapted to regulate the stroke to the power applied to the windwheel bythe force of the wind. 7

Having thus fully described my invention,.

what I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. In a wind-engine, the combination, with the frame of the machine,provided with a wheel shaft having a friction -roller on its crank-pin,of a hinged lever, f, fulcrumed above the crank-pin, and connected tothe upper end of the pump-rod, the wedge on a hearing under said leverf, and the rod it, connecting the wedge i with the spring-pressed hingedlever It, provided with the vane t at its upper end, substantially asspecified.

2. The combination, with the lever f, fulcrumed to the frame at one sideand working between vertical ways at the other side of the frame, of thewheel-shaft having the crankpin provided with a friction-roller, d, thepu1np-rod connected to the lever f, the wedge t, connected by rod n tothe spring-pressed hinged lever It, provided with the vane 2,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto at'fixedmy signature in presence of three witnesses.
